Bitcoin Price Volatility Ahead of Fed Rate Decision and CLARITY Act

Bitcoin is trading below key weekly support levels as investors prepare for a volatile week defined by a widely expected Federal Reserve interest rate hike and a critical Senate vote on the crypto CLARITY Act [1]. The convergence of these two events has prompted a reduction in market risk, with open interest in Bitcoin falling 13.5% over the week ending September 11 [1].

Market positioning and policy pressure

The Federal Reserve is expected to raise benchmark interest rates by 25 basis points to a range of 3.75%–4% on Wednesday, a move driven by persistent inflation and rising oil prices [1]. While market participants previously held a 40% expectation for a rate pause, current data from the CME Group’s FedWatch Tool indicates only a 13.3% probability of rates remaining unchanged [1]. This hawkish outlook coincides with energy market concerns, as analysts warn that potential supply disruptions in the Middle East could impact a significant portion of the 100-million-barrel-per-day global oil market [1].

Simultaneously, the crypto industry faces a legislative milestone on Tuesday as the Senate holds a procedural vote on the CLARITY Act [1]. The bill, which aims to establish a legal framework for digital assets, requires 60 votes to advance to the floor for debate [1]. Despite the significance of the vote, betting markets on Polymarket currently assign only a 34% probability to the bill being signed into law within 2026 [1].

Technical outlook and sentiment

Bitcoin’s price action has struggled to maintain momentum, closing the week at approximately $76,800—below the $78,300 level that analysts identified as necessary to sustain a bullish outlook [1]. The asset also finished below its 50-week exponential moving average of $77,380, a threshold often used to gauge long-term trend health [1].

While spot-market participation remains limited, on-chain data from CryptoQuant suggests that funding rates have gradually increased since the end of May, signaling a shift away from the bearish sentiment that characterized the market earlier in the year [1]. However, current positioning remains roughly 20% below the levels observed prior to the mid-August rally, suggesting that traders have already adjusted their exposure in anticipation of the week's macroeconomic and regulatory catalysts [1].

What to watch

• Senate Vote: The procedural vote on the CLARITY Act scheduled for 2:15 pm ET on Tuesday, which will determine if the bill advances to floor debate [1].
• Fed Decision: The Federal Reserve’s interest rate announcement on Wednesday, specifically whether the central bank opts for the expected 25 basis point hike or a surprise hold [1].
• Support Levels: The 21-week exponential moving average at $72,270, which serves as the next significant technical line of defense for bulls [1].

The market’s primary question remains whether the current derivatives-led momentum can survive the dual pressure of a restrictive monetary policy environment and the outcome of the Senate's legislative process. With Bitcoin failing to reclaim its 50-week moving average, the coming days will likely confirm whether the asset can establish a new support base or if it will revert to earlier, failed breakout patterns [1].
